Big Brother's new Head of Household, Paul Abrahamian, nominated Jessica Graf and Cody Nickson for eviction despite his general knowledge of the couple's "Halting Hex" advantage during Sunday night's Season 19 broadcast on CBS.

Big Brother houseguest Jessica Graf, who is Head of Household this week, won the Power of Veto competition and then chose to keep her original nominations the same during Wednesday night's broadcast on CBS.
